(BMS), said his firm plans to launch Karxt (xanomeline-trospium) in the U.S. as soon as it’s approved by the U.S. FDA, and “expect[s] to accumulate sales in early 2025.” BMS tied a bow on the year by disclosing its plan to pay $330 per share to take over Karuna Therapeutics Inc. in a deal valued at $14 billion to bring aboard Karxt, which acts as a dual M1/M4 muscarinic acetylcholine receptor agonist.
